Application filed December 3C, 190. ml 10. 7 8,436,

invention relates: to collapsible cups, particularly to collapsible cupsadapted for use as shaving cups, and the objects of my invention are:first, to provide a collapsible cup which may be longitudinally extendedto provide a relatively deep, rigid, watertight cup or receptacle, andwhich ma also be readily collapsed into a neat, rigi container orparcel; second, to provide a collapsible cup of this class which, whencollapsed, will provide a convenient container for carrying shavingsoap; third, to provide a cup of this class which, when collapsed andsecured in collapsed form, cannot be readily extended of itself;ifourth, to provide acollapsible cup of this class consisting preferablyof only three members, namely, a. base, an upper member and a cover, thebase being provided with an upwardly extending, cylindrical portionhaving external and internal threads at its upper end, the externalthreads being adapted to secure the upper member in an extended theretoand the internal threads being adapted to receive the cover when the cupis collapsed to form a cover for the same and to secure the upper cupmember rigidly to the base member; fifth, to provide a cup of this classin which the upper cup member may be readily locked in an extendedposition relatively to the base memberagainst an outwardly turned flangeat the upper end of the base member, which flange portion permits awater-tight seal to be formed between the base member and the upper cupmember at the joint; sixth, to provide as a whole a novelty constructedcollapsible cup, and seventh, to provide a cup of this class which issimple and economical of construc tion, durable, and which will notreadily deteriorate or get out of order.

With these and other objects in View, as will appear hereinafter, myinvention consists of certain novel features of construction,combination and arrangement ofparts and portions, as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactorsof reference thereon, which form a part of this application, in which:

My collapsible cup structure consists preferably of only three members,namely, a base i member 1, an upper cup member 2, and a cover 3. Thebase lconsists of a bottom portion 1? and a cylindrical portionextending upwardly from the base I- tlon 1 from near the peripherythereof,

there being provided, however, an annular flange 1 as an extension ofthe bottom portion 1*, which flange extends beyond the periphery of thecylindrical portion 1.. The upper end of the cylindrical portion 1 isprovided with external threads 1 and internal threads 1', which. threadsare preferably formed by rolling the some into the cylindrical portion,thus providing simultaneously, inner and outer threads; The upper end ofthe cylindrical portion 1 is preferably rolled outwardly so that theouter diameter at the upper end is'larger than the outer diameter of theexternal threads. The upper cup member 2 is a cylindrical memberprovided with threads at the lower end, which threads are adapted toengage the external threads 1. when theeup is extended.- Theintermediate portion of the upper cup timber is preferably plain,

The cylindrical portion 3" ot' the cover is alsopreferably rolled to 'form the thread The plate portion 3 of the coveris preterably extended beyond the outer diameter of the cylindricalportion 29, forming .an annular flange 3. WVhen the cup is collapsed, asshown in Fig. 3 oi the drawings, the upper cup member 2 is clampedbetween'the adjacent sides of the annular flange 1 of the base memberand the annular flange 3 of the cover, as shown. When the cup iscollapsed, the inner portions of the threads of the upper cup member'Qengage preferably the outer side oi the cylindrical porand the outsideportion of the flange i engages the inside surface of the plain portionoi the upper cup member so as to provide a non-rattling structure whenthe cup is collapsed. The cup, when collapsed, provides a convenient forcarrying the shaving soap, as shown by dotted lines in Fig. 1.

It will be here noted that when the cup is collapsed and the coversecured in place, a tight compartment is formed between the base member1 and the cover only, the annular extension member or upper cup memberforming no part of the container when the cup is collapsed.

It will be also noted that it it is desired to construct a deepercontainer than shown, the cylindrical portion 1 and the member :2 may beconsiderably lengthened or a plurality of such telescoping members 2 maybe employed.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, I do not wish to be limited tothis particular construction, combination and arrangement, but

desire to include in the scope of my inven tion, the construction,combination and arrangement substantially as set forth in the ap endedclaims.

aving thus described-my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In acollapsible container, a base member having an upwardly extendingcontainer portion provided at its upper end with conforming inner andouter threads, an annu- 1ar extension member positioned in telescopicrelation to the container portion of said base member and provided withthreads at its lower end adapted toengage the threads at one side of theupper end of: said container portion for holding said extension memberin extended relation therewith, and a cover provided with threads at itslower portion adapted to engage the threads at the other side of theupper end of the container portion when said extension member iscollapsed relative to the container portion and form with the latter atight container.

2. In a collapsible container, a base member having a container portion,an annular extension member, the former being provided with externalthreads at its upper end and the latter being provided with internalthreads at its lower end whereby said members may be locked in extendedrelation with each other, said extension member being adapted totelescope around the container portion of the base member, forming a lowcontainer, and a cover having an externally threaded portion at itslower side adapted to be screwed into the upper end of the con tainerportion of the base member.

3.

8. In a collapsible container, a base member having an upwardlyextending cylindrical container portion provided at its upper end withconforming inner and outer threads and at its extreme upper end with asmall outwardly extending flange portion, an annular extension memberpositioned exteriorly of said cylindrical container portion and providedat its lower end with internal threads and above the threaded portionwith an annular flange bearing shoulder, said annular extension memberbeing adapted to be longitudinally extended relativelyto said containerportion with its internal threads adapted to engage the external threadsof the container portion and the small annular flange thereof adapted toseat against the shoulder of the latter, and a cover provided withexternal threads at its lower portion adapted to be screwed into theinternal threads at the upper end of the container portion, forming acontainer with the base member when said annular extension member iscollapsed relatively thereto, said base member and said cover beingprovided with outwardly extending annular flanges respectively at theirlower and upper portions, said annular extension member being adapted tobe clamped between said flanges when the container is collapsed.

9. In acollapsible container, a base member having a container portion,an annular extension member telescopically mounted relatively to thecontainer portion of the former for extending the container portion andfor collapsing the extension member relatively thereto, and a coveradapted to be secured to the upper end of the container portion of thebase member forming a container therewith when said annular exten-' sionmember is collapsed relatively thereto, said base member being providedat the lower portion of its outer side with means for retaining theextension member when the same is collapsed relatively to the base mem-I ber, said cover being provided with means at the upper portion of itsouter side for engaging said extension member when said container iscollapsed.

In testimony whereof, I have hereunto set my hand at San Diego,California, this 19th day of December, 1925.
